Specification ot Letters Patent. Patented Aug. 20, MM2.,

.To all wimmelt may concern: f

Be it known that l, CHARLES J. NASH, aV citizen of the United States, and resident of Chicago, county of Cook, and State of Ill-i-` nois, have invented certain new and useful im rovements in Draft-Gears, of which the fol owing is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invent-ion relates to an improvement in the draft gear which forms the subject of my pending application for Letters Patent Serial No. 664,461, its vobject being to provide an improved form of spacing an retaining plate used in connection with twin spring gears.

As pointed out in the application referred to, the retaining plate is necessarily wrought to its service form in part after the gear is assembled, by bending some of its leaves. The assembling is usually ydone in yards where it is not convenient to heat the parts to be bent, and the purpose of the present in vention is to provide a form of plate which, while lhaving ample body to properly space the springs,`is provided with leaves which, because of their form and relative disposition, may be readily bent as required, without.. 'being heated.

The invention is illustrated in the accom-V panying drawings, in whichl.

Figure 1 is ape'rspective o-f the spacing j and retaining plate, its original forinbeing spacing and retaining plate in service, some arranged side by side, or,

and its service form shown in solid lines,

is a longitudinal verin dotted lines; Fig. 2

` tical section of a draft gear showing the parts of the car construction being shownv in detail; Fig. 3 is a transverse section on the line 3-3 of Fig. 2;

There are shown in the drawings the centrai sills, 10, 11,A of a cai', each being provided w-ith a suitable draft-arm, 12, 1,3; the yoke, 14; a coupler-bar, 15, and forward and rearward followers, 16, 17, the latter being integral with the yoke. There are also shown two sets, 18, 19, of springs, interposed between the follower-plates and as" known in the art, as twins. These two sets of springs are arranged in vertical alinement, engaging, re-

spectively, of the yoke, which are shown as concave, for the purpose of preventing material lateral movement of the springs;

. The springs are spaced apart by means of the spacin' and retaining plate lshown in detail in Fig. 1. This plate is preferably a malleable castin ,having a central body portion, 20, of su cient thickness to properly space the s rings' and provide adequate' leaves, 21, 22, 23, 24, projecting laterally from the body portion and being arranged in pairs, the two members of each pair being spaced apart. While the leaves at either margin of continuous from end-toen, they are preferably made in two pairs, as 'shown,-as being more'easily bent to also for the purpose of reducing weight. Preferably the late is originally cast with its leaves paral el, and without curvature. The two members of each pair of. leaves'may be readily spread and pro rly curved the introduction of a suite le .wed e. The leavesv atA one side of the plate may e roperly spread before the assembling o the the bottom and top side members the plate might'be parts of the gear. The springs having been placed, with the retaining and spacing plate between them, its leaves at one side having been spread, a suitable tool is inserted between the leaves at the opposite side, and by the blows of a hammer will cause the proper spreading, and thus se.- ciirelylock the'` springs within the yoke.

l claim as my invention `1. A spring-spacing comprising `a .body portion anda. pair of leaves rejecting laterally edge o the body and having their adjacent art.

4and retaining; plate l" from each'a side 2. Av spring-spacing and retaining plate cmprisinga body portion and two pairs of leaves projecting edge of the body, the leaves of each pair' havg ing their adjacent two pairs at each side of the b y `being spaced apart laterally. CHARLES J. NASH.
